FILTER'.

VApinreattori" inea september 1s, 192s; serial' No; 663,445;

tube and submerged in a jar or other vessel for filteri'iig'the contientsof theiv'essel assuch con'te1i'tis'-`a.1e siphoned therefrom.`

The.' inventionl seeks,4 as affurther object,

toy provide a filter of such efliciencythat the .filter may be positioned upon the bottoni of the vessel so that practicallytall of? the contents of'th'e vessell may be withdrawn therefrom while any sediment the bottom of the' vessel'l will- `be effectually excluded;

nd the invention? seeks, as a' still further object,- to provide a'- fil-'ter which may be easily takenfapar't and cleaned;

i @ther and incidental objects' will appear hereinafter.

In the drawings Figure 1 is an' elet-ation shoingl" my improved ilter'iniuse',

Figure 2 is a sectional view taken mediallyr through the filter, and

Figure 3| is a horizontal sectional view on Vthe line 3-3 of Figure 2, looking in the direction of the arrows.

In carrying the invention into effect, I employ a filter casing embodying a. conical end plate 10 terminating at its smaller end in Ya neck 11 and appropriately `secured to the lower side of the plate at the base of the neck is a concentrically arranged ring 12 having an inwardly directed annular flange Removably threaded into said ring is a cylindrical shell 14 and removably threaded upon the shell at its lower end is a clamping ring 15 having an inwardly directed annular fia-nge 16 extending beneath the lower end edge of the shell. The end plate 10 of the casing overhangs the shell and is formed at its base end with a depending annular flange 17, and connected t-o said plate is a skeleton supporting frame en bodying a plurality of strips or legs 18 soldered or otherwise secured at their free ends to the flange 17 while to the lower ends of said legs is similarly secured a channelshaped base ring 19, Removably threaded upon the neck 11 of the filter casing is ai cap 2O from which rises a preferably stepped yout-let nipple 21, and removably engaged over said nipple is a Siphon tube 22. Formed on the neck 11 at its upper enfd is'an inwardly directed annular flange and clampedbetween the cap and said flange'i's a yield'ahle gasket 24 forming' a' sealedi joint between the capi and neck.

Fitting in thering 12 of the filter casing 1 y is ayieldablje gasket 25 and formed on' the shell' lll' ati its upper end to coact with said gasket is an inwardly directed' annular flange 26 while between the gasket and the flange 1 3 of said ring is interposed a lter cloth 27. Thus, as will be seen, the shelll 121 nay be adjusted upon the ring12to bind inst the gasket so as to forni a sealed )lint between the shell and ring while the gasket will he compressed against the filter cloth for holding said cloth against' aceidental displacement. A t its lower end'7 the shell is formed with ai flange 28 similar to the flange 26 and confined within the shell between said fiangesis sponge 29. interposed between the flange 28 ofthe shell and theflange 1G of the ring' 15` is a yieldable gasket 30 and interposed between said 'gasket and the flange 16 is a' filter cloth riccordingly, the ring 15 may be adjusted upon the shell for compressing the gasket to form a tight joint between the ring and shell and clamping' thel filter cloth in place. Enclosing the filter casing is a cloth filter sack 32 fitting over the sup-porting frame of the casing and secured at its mouth tightly around the tube 22 by a draw string 33.

In Figure 1 of the dra-wings, I have shown my improved filter in use, a vessel being` conventionally illustrated at 34 and an ordinary bottle at 35. As shown, the filter rests upon the bottom of the vessel and the tube is e1nployed to siphon the contents of the vessel into the bottle. As the contents of the vessel are thus drawn through the filter, it will be seen that the fluid must first pass through the filter sack 32, which will serve to eliminate all heavier particles from the fluid. The fluid will then be drawn through the cloth 31 at the lower end of the filter casing which will serve to eliminate particles not excluded by the sack 32. The fluid will then, of course, be drawn through the sponge 29 to be further filtered by said sponge and then through the filter cloth 27 to be finally filtered by said cloth, Accordingly, all sediment or other particles will be effectually eliminated from the fluid so that the fluid will issue from the filter in a perfectly clear state. In this connection, it is vto loe noted that the supporting frame for the fiiter casing will support the lower end of said casing out of cont-act with the bottom of the vessel but close thereto- Accordingly, practically all of the contents of the vessel may be siphoned therefrom.

Having thus described the invention, what is claimed as new is:

l. A filter comprising a unit for disposal bodily within a container and including a shell having an inlet and an outlet, filtering means within the shell, a frame mounting the shell and extending below the inlet thereof to rest against the bottom of the container supporting said inlet above the bottorn of the container, and a filtering sack enveloping the frame and shell for excluding heavier particles from said inlet, the sack being exposed for free removal.

2. A filter comprising a unit for disposal bodily within a container and including a shell having an inlet and an outlet, a sack envelopingthe shell and forming the outer cover of the unit exposed directly to the contents of the container to provide a primary filtering means excluding the heavier particles of said contents, the sack being freely removable, and a secondary filtering means enclosed within the shell.

3. A filter comprising a unit for disposal bodily within a container and including a shell having an inlet and' an outlet nipple, a frame mounting the shell and extending below the inlet thereof to rest against the bottom of the container supporting Said inlet above the bottom of the container, a sack enveloping the frame and shell and provided at its mouth with a draw string tied around said nipple, the sack forming the outer cover of the unit exposed directly to the contents of the container to provide a primary filtering means excluding the heavier particles of said contents, and a secondary filtering means disposed within the shell.

4. A filter including a top plate provided centrally with a discharge neck, a ring fixed to the lower side of the plate at the base of said neck, an open-ended shell screwed at its upper end in' said ring, a filter cloth clamped wit-hin the ring to overlie the adjacent end of the shell, a second ring screwed upon the lower end of the shell, a second filter cloth clamped within the latter ring to overlie the lower end of the shell, a filtering `sponge disposed within the shell between said cloths, legs fixed to the top plate near its outer edge and extending below the lower end of the shell, and a base ring secured to and connecting the lower ends of the legs with each other.

5. A filter including a conical top plate provided with a discharge neck, an openended shell connected with said plate at the base of said neck and communicating with the neck, ltering means disposed within the shell, legs fixed to said top plate near the periphery thereof and extending below the lower endof said shell and a base ring` secured to and connecting the lower ends of the legs with each other.

In testimony whereof I affix my signature.
